What's this test for?
This test is ideal if you're experiencing symptoms like dehydration, persistent weakness, confusion, irregular heartbeat, or unexplained vomiting. It helps identify electrolyte imbalances and acid-base problems that can affect your heart rhythm, kidney function, and breathing. Many people use this test when they have ongoing symptoms that might indicate their body's fluid and mineral balance is off.
What's included in this test?
This panel evaluates your body's electrolyte and acid-base balance through sodium, potassium, chloride, and carbon dioxide levels, which are essential for proper heart function, nerve signaling, and hydration. The calculated anion gap helps identify metabolic acidosis and kidney problems. Together, these measurements provide a complete picture of your fluid balance, respiratory health, and metabolic function that can explain symptoms like weakness, confusion, and irregular heartbeat.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your electrolyte levels mean for your hydration, heart health, and overall balance. These notes include personalized recommendations like dietary changes to restore electrolyte balance, hydration strategies, or when to follow up with a doctor if levels are concerning. You'll also get the standard lab report and can track your electrolyte levels over time using our trends feature to see how your interventions are working.
Who should consider getting this test?
This test is important for people experiencing dehydration, weakness, confusion, or heart palpitations. It's also valuable for those with chronic conditions like kidney disease or diabetes, people who've had severe vomiting or diarrhea, and anyone taking medications that can affect electrolyte balance like diuretics or blood pressure medications.
What symptoms indicate I may need this test?
Common symptoms include persistent weakness or fatigue, confusion or difficulty concentrating, muscle cramps or twitching, irregular heartbeat or palpitations, and frequent dehydration despite drinking fluids. You may also need this test if you're experiencing nausea, vomiting, swelling in your hands or feet, or feeling dizzy when standing up.
How can I maintain healthy electrolyte balance?
Stay properly hydrated by drinking water throughout the day, especially during exercise or hot weather. Eat a balanced diet rich in fruits and vegetables that provide natural sodium, potassium, and minerals like bananas, leafy greens, avocados, and sweet potatoes. If you exercise heavily or sweat a lot, consider electrolyte-containing drinks, and be mindful of excessive sodium intake from processed foods.
What is the anion gap and why does it matter?
The anion gap is a calculated value that measures the difference between positively and negatively charged electrolytes in your blood. It helps doctors identify the cause of acid-base imbalances, particularly metabolic acidosis, which can result from kidney disease, uncontrolled diabetes, or other serious conditions. An abnormal anion gap can provide important clues about what's causing your symptoms.
What does high potassium mean?
High potassium (hyperkalemia) can be dangerous because it affects your heart's electrical activity and may cause irregular heartbeats. It can result from kidney problems, certain medications, dehydration, or consuming too many potassium-rich foods or supplements. If your potassium is high, your doctor may recommend dietary changes, adjusting medications, or addressing underlying kidney issues.
What does low sodium mean?
Low sodium (hyponatremia) means you have too little sodium in your blood relative to water, which can cause confusion, weakness, and in severe cases, seizures. It can happen from drinking too much water, certain medications, heart or kidney problems, or losing sodium through sweating or vomiting. Treatment typically involves addressing the underlying cause and carefully adjusting fluid and sodium intake.
How often should I retest my electrolyte levels?
If you have a chronic condition affecting electrolytes like kidney disease or are on medications that alter electrolyte balance, your doctor may recommend testing every 3-6 months or more frequently. For acute issues like severe dehydration or illness, retesting may be needed within days to weeks. If your initial test is normal but you develop new symptoms, retesting when symptoms occur can help identify the cause.

What this means
Your potassium level is slightly below the optimal range, which can contribute to muscle weakness, fatigue, and cramping. Low potassium may result from dehydration, certain medications, or inadequate dietary intake, and it's important to address to maintain proper heart and muscle function.
Recommended actions
Include more potassium-rich foods like bananas, sweet potatoes, spinach, and avocados in your diet
Stay properly hydrated throughout the day, especially if exercising or in hot weather
Review medications with your doctor that may affect potassium levels like diuretics
Retest in 4-6 weeks after dietary changes to ensure levels normalize
* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
